Coming from a Quaker background this sounds like an "advice and query" but i think it's appropriate for work too - so.... esp maybe, in a quiet library "Open your mouth only if what you are going to say is more beautiful than silence."
George Lakey, a Swarthmore professor, explaines the origins and rationalism of pacifism in the Quaker religion. He states that the spirit Quaker's believe in is not contradictory or hypocritical, it will not call for peace, love and understanding one moment and then war another. The spirit Quaker’s believe in is consistent. He goes on to give historical groundings for Quaker’s belief in pacifism. Later in his talk he makes the claim that nonviolence movements are more effective.
